The G5 iMac was 17 years ago? How the tempus doth fugit.
I bought one of these iMacs for my (then) partner, expecting that she'd use the Mac and I'd continue to use Linux (Gentoo back then) for my main PC and Windows for games. I played around with Mac because I though that knowledge of OS X might be useful (and it was Unix underneath). What I didn't expect was that I started to use the Mac for almost everything and, eventually, retired the Windows and Linux machine and switched completely to Mac.
These days, we've still got Macs at home for everyday use, plus a couple of Linux Mint machines for WFH and NAS.
